To ALL WHOM IT Mar concurran Be it known that we,'W1LLmM M. RUSSELL and D. E. HOLMES, both of Cincinnati, county o Hamilton,

and State of Ohio, have invented. certain n'cwand useful Improvements in Railroad-Cnr Ventilators; and Wc do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, and the letters oi' reference marked thereon, making part of this specification, in whiclii figure 1 is a plan view of a railroad-car window, sash, the.

Fignre`2is aside sectional view of' the same, and an additional vicw'at the line y y being also given.

Figure 3 is a` view of my defleetor detached from the window, and an additional sectional view at the liuc a: a: being also given. v I

Figure 4 is atop side view of a car, with dclleetors attached, the arrow at a; indicating their position when the car is travelling in one direction, and y indicating their position when they travel in the opposite direction.

The object of our present invention is to furnish railroad-cars witha deflector, so arranged that it can readily be attached to or detached from the ear, as occasion requires. Itacts 4very-.much upon the same principle with our invention of even date herewith, but differs entirely in construction and` arrangement. Instead of the double series of blinds, a singlc'one only is required. It being portable, and secured in position by no -permanent attachment, its relative position can be readily changed at pleasure; and thus we are enabled, by the vemployment of a single blind at each window, it matters Anot in what direction thc car may be travelling, to eectually exclude all dust, ruin, sparks, and cinders from the car, which cil'cct is produced by causing the current of hot and impure air to pass from the interior of the car outward, through thc window, by exhaustion.

The nature of ouriuvention consists in securing a slot, provided in a suitable block of wobd, a blind or detlector, constructed of a plain oblong board. The dimensions of the block arc such that it fits snugly in the groove 'inwhiclr works the sash. The block is provided with projecting pins, which enter suitable openings provided in the base of the window and the lower surface ofthe sash-frame. When our detlector is' in position, the block acts as a prope r-stiek, to retain the sash in an elevated position.

The great advantages possessed by our arrangement et' dcectors will readily suggest themselves to any one in the Ileast degree familiar with the class or" invention to which it pertains. i

First, its great durability, chenpness, and extreme simplicity, it being entirely free of all operatingmechanism. There are no features to become deranged or thrown out et' order. The materials used can be readily procured at any market or depot, while its simplicity o` construction is such that the most unskilled mechanic can readily make and apply the same. l

Another great advantage consists in the i'act that a s et ol' our dcllectors can readily be applied to any car, and also changed from car to car, as occasion requires. And when not in use, simply 'oy elevating the sash an inch or so, the deilector can be removed and placed under the scat, or left at some other convenient point.

To enable others' skilled in thc art to make aud'usc our invention, we willnow proceed to describe its construction and operation. l

A is a railroad-car, constructed in the usual manner, as are also the frame B and sash C, with the exception that the base of the former is inclinedltowards its outer edge, as shown at i), iig. 2, while the lower frame .ofthe lutter inclincs at a lilgc angle, yas shown at c, salueigure.

'lhe advantages gained by this'i'orm of base are that the face oi' the deflector D being sloped to correspond, when in position, as shown in lig. I2, it is firmly held, the formation ofthe base being such as to allow but little play, no matter how great the current of nir may be through which it is passing, while, if the base were level, almost the entire strain would have to be borne by the sash and its strip c2. i

D is a dcflcctor or blind, and is simply a plain board, oblong in form, the inner edge of' its upper surface being slightly curved, as shown at d, while the inner edge of its lower surface is slightly sloped in an angular direction, as shown at el.

One edge of the deflector D Iits and is securely fastened in a slot, e2, of tho block E. This block E is rectangular in form, its length being alittle less than the distance the sash C is allowed to run in the groove c. Its dimensions are such that it ts in the groove c. The upper and lower edges ofthe block E are cut slightly angular, their `formation, in,this regard, corresponding exactly with that of the bese, 6, and the*l lower frame c of the sash. On the ends of the block there are projecting pins ee. These pins fit in suitable openings in the frame and sash, as'elearly shown in lfig. 2.

lThe operation is as follows:

The sash is elevated'in'the position shown in fig. 1. The deilcctor D is then applied to the window, the block E litting 'inthe groovo'c, the lower pins el entering suitable openings in the base, c. The sash is then permitted to fall, theupper pins c entering suitable openings in the lower frame c of the sash. The window and deflector will then occupy the relative positions shown in fig. 2, and the whole series of delectors will occupy the position sl1own-atwx,iig.4, the direction in which the car is travelling being indicated by the arrow. Should theicar be required to travel in the opposite direction, it is only necessary to lift the sash, and shift the detlectorto the other side of the frame, to'thc position shown at y y.

Having thus fully described our invention.l whatwe claim therein as new, and desire to secure by Letters Patent of the United States,lis- A The `delector D E, when the same is provided with projecting pins e c', in combination with the angular i hase, b, and sash C, and the whole is so constructed and arranged as to operate substantially as described and for the purpose specified.

In testimony whereof, we have signed our naines to this specification in the presence of two subscribing witnesses.
